Precision Machining Steps
Nov 21, 2018

1. Finishing: This processing principle is roughly the processing of some polishing and polishing, which is usually the step after the product has completed the architecture.

2. First face back hole: When carrying out precision mechanical parts, for a workpiece such as a bracket, it must be both planar and mechanically machined. For the accuracy of the hole being machined, the machining accuracy is smaller. The post-processing holes help to reduce the error.

3. Division of processing stage: When the product is in precision mechanical parts, it must be processed according to different product requirements. The degree of processing needs to be divided. If the accuracy is not high, then a simple roughing stage is required. The progress requirements of the products are becoming more and more strict, and the semi-finishing and finishing stages are followed.

4. Benchmark first: When using mechanical equipment to process the product, it is necessary to determine a datum surface so that there is a positioning reference in the subsequent processing. After the datum is determined, the datum surface is first processed. In precision mechanical parts, there are many workpieces that are not produced by one-off production, but when the workpiece is produced, it is just a rough model.
